Select the right "Krishna" bimetal. The performance of TOP is dependent upon the applied current. Where if the temperature rise is less than 2°C per second. use low resistance bimetal. If the temperature rise is 2°C - 5°C per second, use high resistance bimetal. If the rate of temperature rise exceeds 5°C per second. contact our qualified QC staff for technical assistance.
